Computer logic-centered

That there is a need for such an application is made apparent by the fact that a complete, logic-centered synthetic analysis of a complex organic structure often requires so much time, even of the most skilled chemist, as to endanger or remove the feasibility of the approach. It would be a great advantage if at least a part of the necessary analysis could be performed rapidly and accurately by computer. ... 

For purposes of this discussion, attention is focused on the yield response variable, yr Notice first that the four y2 values from the center point of the experimental region have y = 53.2 and s= 1.13 (which incidentally already appear to be an improvement over typical process behavior). As a partial indication of the logic that can be used to investigate whether the dependence of yield on the experimental factors is simple enough to be described adequately by the data of Table 5.7, one can compute some estimated main effects from the first eight data points. That is, considering first the impact of the variable Xj (alone) on yield, the quantity... 

In many of the early applications of fuzzy logic, the s and B s in the if-then rules had to be calibrated by cut-and-trial to achieve a desired level of performance. During the past few years, however, the techniques related to the induction of rules from observations have been developed to a point where the calibration of rules—by induction from input-output pairs—can be automated in a wide variety of cases. Particularly effective in this regard are techniques centered on the use of neural network methods and genetic computing for purposes of system identification and optimization. Many of the so-called neuro-fuzzy and fuzzy-genetic systems are of this type. 

The ALU is a combinational circuit, and is that part of the processor that performs arithmetic, logic, and other necessary related operations. Sometimes there is a separate component, shifter, which is used to perform the shift operations on data items. The abstraction 2 programmer usually considers the shifter activities to be a part of the ALU. The Abacus, Blaise Pascal machine, and other ancestors of the computer were really just ALUs, and for the most part the other components of modem computer systems are merely there to hold data for or transfer it to the ALU. Thus, the ALU could be considered the center of the computer system. However, it does not determine its own activities. Abstraction 1 or 2 instructions determine its activity via the control. The ALU will be actively involved in steps 2, 3, and 5 of the instruction cycle of Example VIB and may be involved in other steps.
